摘要

This research aims to present a sensorless direct field oriented control (DFOC) with intelligent technique based on fuzzy logic controllers (FLC) to obtain fast response and to improve the dynamic performance of a three-phase induction motor drive (IM). These regulators are applied in speed, flux and stator currents control of induction motor. A Luenberger flux observer and speed adaptation are associated with the proposed scheme. Simulation results show that the proposed direct field oriented control with the proposed observer provides good performance dynamic characteristics for different operating modes. The robustness of the overall system is studied using simulation for load torque disturbance.
